The successful implementation of CCUS requires the confluence of technology, regulatory, and financial factors. One of the factors
that impact this confluence is the ability to utilize and monetize captured CO2. The ...

Microfiltration can increase the service life of metalworking fluid by removing contaminants. However, membranes quickly become clogged, a process known as fouling. Anti-fouling methods in practice in the mid-2000s involved ...

Some metalworking fluids are designed to coat the surfaces of newly machined metal with rust inhibitors. At some point, these inhibitors are expected to become depleted in the metalworking fluid. How quickly does this ...

The use of ultrafiltration (UF) applications with alkaline cleaners was a common practice as of 2001, but at the time UF was still susceptible to fouling and stripping out active agents from the cleaners. ISTC’s Kishore ...

Metalworking fluids are used for cooling, lubrication, and corrosion control in the metal products industry. As of the mid-2000s, many manufacturers were using filtration or centrifugal systems to remove impurities from ...

It was initially thought that no metalworking fluid could be developed to meet industry specifications and be compatible with membranes to use microfiltration to remove contaminants. However, Rajagopalan’s team developed ...

Kishore Rajagopalan and his colleague explored how contaminants like tramp oils and salts impact the productivity of recycled metalworking fluids. They found that metalworking fluids had no losses in cooling and lubricating ...

A ceramic membrane filtration system can be an effective tool to increase the lifespan of medalworking fluids and reduce biological hazards. However, the usefulness of the membranes may be reduced by different additives ...

The work summarized in this report is the first step towards a project that will re-train and create jobs for personnel in the coal industry and continue regional economic development to benefit regions impacted by previous ...

Metalworking fluids are designed to perform specified tasks in the factory. However, these fluids can become contaminated during the manufacturing process by other factory components such as tramp oil. As more and more ...

ISTC’s Kishore Rajagopalan and colleagues from the University of Illinois discovered that partial blocking of pore spaces from microemulsion aggregation was a new fouling mechanism leading to total pore space blocking and ...

Since the early 2000s, industries have faced rising costs to acquire, manage, and dispose of metalworking fluids, as well as increased concern about pathogenic bacteria growing in metalworking processes. The need to reduce ...

Metalworking fluids are an emulsion of oil in water. The emulsion stability goes down with increased harness ions such as calcium and magnesium. Typical tests for emulsion stability involve the determination of oil losses ...

Biochar is a charred carbon-enriched material intended to be used as a soil amendment to sequester carbon and enhance soil quality. Sustainable biochar is produced from waste biomass using modern thermochemcial technologies. ...

The U.S. Forestry Service (USFS) engaged sustainability experts at the University of Illinois, Western Illinois University (WIU), and the Metropolitan Mayors Caucus to investigate the use of wood waste by businesses as a ...
